- Any session operation that hits 404/410 (or finds no open tab) reconciles
tabs; if none survive it re-injects the account cookies (BR-2), opens a new
tab under the same userId/sessionKey, returns to the recorded URL (site home
otherwise), marks old tabs lost and retries the operation once. Failure
returns 503 browser_reconnect_failed with the reason, with a 10s backoff.
- Restart detection: umt plugin GET /umt/instance (fallback /health fields);
a changed instance id marks every open session needsReconnect.
- POST /browser/sessions/{id}/reconnect (idempotent); session view exposes
needsReconnect and reconnect {status, trigger, at, reason, humanNotice}.
- Controller and lease are kept; reconnecting during takeover asks the human
to double-check the reloaded page.
- Web: screenshot and desktop modes show "reconnecting", auto-reconnect once,
pause polling, offer a reconnect button with the reason on failure; desktop
mode rebuilds the Selkies connection after a reconnect.
- Mock camofox restart(), tests, smoke step and runbook section 10.

- compose: camofox service on by default (internal only, volume umt-camofox,
healthcheck, CAMOFOX_REPLICAS=0 to skip); app depends on it with
service_started/required=false and auto-registers camofox-env from
BROWSER_PROVIDER_URL / BROWSER_ACCESS_KEY / BROWSER_ENABLED
- docker/camofox/Dockerfile: builds upstream tag v1.17.0 (389c996); fixes the
upstream Dockerfile (missing postinstall.js before npm ci, sh -c not
forwarding SIGTERM so logins were never persisted on restart)
- adapter fixes from the real container: coordinate click via evaluate +
selector, focus typing with mode=keyboard, password values redacted from
ARIA snapshots/extract, downloads field names, 410 after browser restart
treated as lost tab; navigate reopens a tab in the same session
- verified-capability table keyed by upstream version (1.17.0 all ten);
other versions stay unverified; probe reports auth failures
- settings: browser providers block (create/edit/delete/probe, capability
table); API POST/PATCH/DELETE /browser/providers, POST .../probe
- scripts/browser-verify: umtbr stack + mock NexusPHP run of REQ 4.7.4 items
- docs: runbook browser §1/§7 (real-instance record), deploy §2.1
